Ok - Almost all my customers are in a similar situation as far as their setup:
Desk Phones -> Local ISP -> Internet -> FreePBX Hosted at Vultr -> Internet -> Trunking Provider
Here is my question - Do you all know any way (with a Linux Box at the Customer Site) that I could isolate where the problem is actually coming from? Some cool Linux utility that looks at the Network Hops and can break them out as to where we are being let down?
I know I could use Traceroute to show me the times on the individual hops, but I need more info than that - basically I need to be able to isolate who is dropping the ball on the connections.
I am hoping there is a utility/suite that I could run on the On-Premise Box and the Co-Located box that would provide the smoking gun - i.e.:
Customer Site to Vultr Miami - Perfect
Vultr Miami to ITSP - High Latency and dropped packets utilizing Zayo (or Level(3) or whoever)
I just tried to track down a problem I had yesterday and it involved three calls with everyone (the ISP and the Hosting company) claiming there was no problems, and yet the ITSP gives me a MOS score graph for the duration of the call showing it started out good and went downhill until it dropped.
Anybody have any cool ideas about this?
